The backup is scheduled several times a day and there is a second server in another data center that works in parallel, it will work if the first one stops responding. We are testing a DDOS attack right now, so far the results are good. We will connect to Cloudflare protection if it gets really bad.
Names, passwords and emails are stored in encrypted form, we do not collect or store payment data. The owner of the tag can delete messages in chats and chats themselves, so you have almost complete control over your data within your account.
If you find a vulnerability, we will reward you and publish a confirmation (if you need for a CV).
